は一般に温度Ｔの函数であつて、第１図に示すよ
うに温度が高い程、平衡分解圧も大きい。 It is known that certain metals and alloys exothermically absorb hydrogen to form metal hydrides, and that these metal hydrides reversibly and endothermically release hydrogen. The equilibrium decomposition pressure P of such a metal hydride
is generally a function of temperature T, and as shown in FIG. 1, the higher the temperature, the greater the equilibrium decomposition pressure.

媒を流通させる際の熱損失も大きい。 In recent years, various heat pump devices have been proposed that utilize these properties of metal hydrides.
In most cases, metal hydrides with different equilibrium decomposition pressure characteristics are filled into sealed containers that form a heat exchanger, and hydrogen is endothermically released from the metal hydride in one heat exchanger, and this hydrogen is transferred to the other heat exchanger. The operation of introducing the heat exchanger to the metal hydride and occluding it in the other metal hydride is repeated alternately for each heat exchanger, and the heat generated or absorbed by the metal hydride is extracted as output from each heat exchanger in a batch system. Therefore, such a heat pump device requires a complicated heat medium circuit and a control mechanism therefor in order to alternately heat or cool each heat exchanger, and since the heat medium circuit itself has a heat capacity, the heat medium Heat loss is also large when heat mediums of different temperatures are passed through the circuit.

媒には連続して冷熱が与えられる。 The operation when the above device is used for cooling will be explained based on FIG. 3. M 1 H is cooled by the medium temperature heat medium at temperature T M in the medium temperature heat exchange section 8, while the hydrogen pipe 10
(point C). This hydrogen is released while M 2 H absorbs heat from the low-temperature heat medium in the low-temperature heat exchange section 14 (point D). The low temperature heat medium is connected to the cooling load and performs the cooling function. The M 1 H that has absorbed hydrogen is then transferred to the high temperature heat exchange section 9.
It is heated to a temperature T H and releases hydrogen (point A), and this hydrogen is sent to the intermediate temperature heat exchange section 15 of the second cylinder via the hydrogen pipe 11, where it is cooled to a temperature T M and is converted to M 2 H is occluded (point B). The M 1 H is recycled to the feed port and the M 2 H is returned to the feed port 4' to start a new cycle. In this way, cold heat is continuously applied to the low-temperature heating medium.

The axial diameter of the screw may be gradually increased by pinching 0, and at the same time the pitch of the screw may be gradually reduced. can be made smaller. As a result, the metal hydride is compressed as it approaches the heat exchange section, and the flow of hydrogen in the axial direction of the cylinder is blocked, so the heat exchange section is pressure-blocked, and therefore each The hydrogen storage and release reactions of the metal hydride in the heat exchange section can be carried out at a predetermined pressure level.

高い。 As described above, according to the apparatus of the present invention, the metal hydride is transferred continuously while exchanging heat with the heating medium at a fixed position, so the heating medium circuit is alternately switched to exchange heat with the reaction vessel. Unlike conventional devices that provide heat transfer, essentially continuous heat output can be obtained without switching the heating medium circuit, and the coefficient of performance is high.
